Abstract

A fan (60) with a sound-muffling box has, inside a machine body (3), a double-suction centrifugal fan (9). A suction-opening sound absorption member (11) is provided between a machine body suction-opening (1) and the double-suction centrifugal fan (9). The fan (60) further has an airflow path (26) of the casing suction-opening side and a first airflow path (27), which has a triangular prism shape, in the suction-opening sound absorption member. The fan (60) with a sound-muffling box has a reduced pressure loss, requires less input, has increased static pressure, and has suppressed airflow collision noise.
